Let's divide 783488 by 90
We want to figure out the number of times 783488 can be divided by 90.

Let's proceed to step 1:
7 divided by 90 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 90

Advancing to step 2:
78 divided by 90 is 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Append the next digit (3) from the dividend to 78 and continue with: 783 / 90

Let's proceed to step 3:
If we divide 783 by 90, we get 8 and a remainder of 63.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 720 from 783 to get 63.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 90

Let's proceed to step 4:
634 divided by 90 is 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 87.0
Deduct 630 from 634 and we're left with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 90

Going ahead to step 5:
If we divide 48 by 90, we get 0 and a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 870.0
The remainder is 48 after subtracting 0 from 48.
Take the next digit (8) from the dividend and append it to 48, then repeat: 488 / 90

On to step 6:
488 divided by 90 is 5 with a remainder of 38.
Write down 5 as next digit of the result. 
Result so far: 8705.0
Deduct 450 from 488 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
90 goes into 380 4 times with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 8705.4
The remainder is 20 after subtracting 360 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
When dividing 200 by 90, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 8705.42
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
200 divided by 90 is 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 8705.422
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 8705.422 with a remaining 0.002.
